The SITAS 4AM6442-8ED40-0FA0 is a 2000VA single-phase control transformer with a high-range three-tap primary spanning 575/550/525V, stepping down to 230V at 8.70A. The highest-power SITAS transformer available with the 575V primary range — designed for Canadian and heavy-industrial installations where mains voltage reaches the highest standard levels.

Electrical Performance

Rated at 2,000VA continuous with a short-time power rating of 9,700VA (S6 duty) — nearly 5x headroom for high-inrush loads. The EI 174/102 laminated core achieves approximately 96 percent efficiency. Full galvanic isolation via II0 vector group.

Mechanical Design

Substantial 158x176x164mm IP00 open-frame construction for enclosure installation with screw terminals and screw mounting. Class B (130 C) insulation system, rated for 40 C ambient. Weighs approximately 25 kg.

Application

Suited for the largest control panels in facilities with 575V distribution — Canadian manufacturing plants, South American heavy industry, and specialized process installations — where 230V control power is required at the maximum SITAS power rating.
